Vamac®GXF
Ethylene Acrylic Elastomer
DuPont Performance Elastomers
产品说明:
DuPont™ Vamac® GXF is a terpolymer of ethylene, methylacrylate,and a cure site monomer cured using an amine-based vulcanizationsystem. Compared with Vamac® G, Vamac® GXF has improved hightemperature properties and better dynamic flex fatigue resistance.Vamac® GXF includes a small amount of processing aid, and has anominal specific gravity of 1.03. It has a mild acrylic odor. Useadequate ventilation during storage, mixing, and processing toprevent accumulation of residual vapors. Storage stability isexcellent.
Vamac® GXF is well suited for those applications which needimproved high temperature properties or improved dynamic flexfatigue resistance over Vamac® G and can tolerate a slightly longercure time. Typical applications that would benefit from theimproved properties of Vamac® GXF are air ducts, hoses andtorsional dampers.
Compounds of Vamac® GXF compared to Vamac® G have longer scorchtime for improved processing and slightly higher compression sets.Elongation and properties at elevated temperature are improvedresulting in significantly improved dynamic flex fatigueresistance. Heat and fluid aging is similar.
Vamac® GXF is well suited for injection, transfer and compressionmolding, and is easily extruded.
